Hello, I'm currently working on some creative writing which takes place during the Civil War, and at one point the main character breaks his arm during a battle, from a fall not gunfire or etc, far behind enemy lines. My question is would a military surgeon be able to set a broken bone even if the solider took several days to get back to his regiment, or would they amputate it? I know Minnie balls would often tear tissue and shatter bone, and that infections were also a major reason for amputation, but that is not the case in my story, so would they simply set the bone? Did they use casts for broken limbs like we do today or something else? Thanks, for your time.
